Welcome to the HELCOM coastal fish core indicator database (COOL).
This database contains updated data used in coastal fish core indicators
for every current monitoring station in the Baltic Sea and information
on the latest status assessment for the indicators.
The Core indicators are:
Abundance of coastal fish key functional groups, which is based on
the abundance/biomass of piscivores and abundance/biomass of cyprinids
Abundance of key coastal fish species, which
dependent on area is based on the abundance/biomass
of perch, flounder or cod.
